CAR BRAKE AND STARTER.

SPECIFICATION forming part of Letters Patent No. 339,645, dated April13, 1886,

Application filed August 3, 1885. Serial No. 173,453. (No model.)

To all wh'om it 17mg concern.-

Be it known that I, DANIEL HALL, acitizen of the United States, residingat Gault, in the county of Grundy and State of Missouri, have inventedcertain new and useful Improve ments in Car Brakes and Starters, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention is particularly adapted to horse-cars; and it consistsin anovel construction, arrangement, and operation of devices for stopping acar and for storing power to assist in starting, as hereinafter moreparticularly described.

In the accompanying drawings, Figure l is a top view of a mechanismembodying my improvements. Fig. 2 is a View of one of the axles anddevices attached thereto. Fig. 3 is a vertical section taken in the line:0 a: ofFig. 2. Fig. 4. is a verticalsection taken in theline pg; ofFig. 1. Figs. 5, 6, 7, and 8 are detail views.

A represents the axle, and B the wheels, of a horse-railway car.Surrounding the axle, extending part of its length, isa sleeve, 0,provided near its ends with oil cups or holes and suitable bearings, andhaving its intermediate interior surface grooved or concave, so as toallow free circulation of oil between the sleeve and the axle. Near oneend of the sleeve is a drum, D, formed of two disks connected by rods orbars surrounded by a hand or tire. In this drum is a coiled spring, E,the outer end of which is attached to one of the rods or bars of thedrum, and the inner end is attached to the sleeve C. Between one end ofthe drum and the contiguous end of the axle is a disk, G, which is keyedto the car-axle so as to turn with it. In the inner face of this disk isa series of acute depressions or pockets, y, and the corresponding faceof the end of the drum is provided with spring-pawls d, for engagementwith said acute depressions or pocket-s. On the opposite end of thesleeve, attached to or forming a part of the drum, is a disk, H, havingobtuse holes or pockets f in its outer face. Between this disk and theend of the axle is a disk, J, which is feathered to 5 the axle so as toturn with it. The inner face of this disk is provided with obtuse pawlsi, for engagement with the obtuse holes or pockets f in the disk H.

Between the disks H and J is an int-ermedial disk, I, provided withholes through which the bolts i and pawlsi pass to engage with the holesor pockets f. These two disks II and J form a clutch, and the two partsare thrown into engagement bya forked lever, K, the front end of whichrests in aframe at the front end of the ear, and the other endissuitably secured by hinge or pivot joint. A spring, 7.1, has atendency to press the lever outward.

Instead of the clutch above described, the ratchet-toothed form ofclutch shown in Fi 5 may be used.

- On the inner side of the disk H is a series of notches, h, (see Fi 6,)for engagementwith a pawl, L, pivoted to the sleeve G, and pro 3'..-vided with two springs, Z in, one for engaging it with the notches h andthe other for disengaging it. To the pawl L is attached one end of acord or chain, M, which passes around. pulleys, and has its other endattached to the 7 5 lever K.

X is a frame composed of curved pieces as and :0 extending over theaxles, and properly journaled to the same with pieces 2: and a2,connecting them together from front to rear.

From the under side of the rear portion of the frame X extends a hanger,p, to which is pivoted the rear end of a clamping-brake consisting oftwo rigid strips or bars, P P, which are curved to embrace the upper andlower surfaces of the band or tire s of the drum 1), and which have aspring, (1, between them to keep them disengaged from the tire s whennot in use. The front ends of these bars are passed through acompressing device, Q, con- 96 sisting of two rectangular frames pivotedtogether somewhat after the manner of a sawbuck. The upper end of one ofthe frames is hinged or pivoted to the under side of the platform orframe X, and the lower end of the other frame has attached to ita cordor chain. R, which passes over a pulley and is attached to thebrake-operating crank-handled brakeshaft T.

To the lever K, between the fulcrum and the 00 outer end, is attachedone end of a cord or chain, S, which passes around a pulley and isattached to the brake-shaft, T.

The parts being thus constructed and arranged, when the brake-shaft T isturned the rod, link,or chain It andS is wound around two shaftssimultaneously. By this means the clamping-brake 1? is compressed, so asto bear on the upper and lower surfaces of the band or tire of the drumD. At the same time the action of the lever K throws the clutch J intoengagement and winds up or compresses the spring E, while the slackeningof the cord or chain M. allows the spring at to engage the pawl L withthe notches h and prevent the spring E from unwinding, and the car isbrought to a full stop. \Vhen the brakeshaft is turned in the oppositedirection, the spring it throws the lever K outward and disengages theclutch, and the unwinding of the spring E turns the axle and assists instarting the car by turning the drum D forward. The pawls d, engagingthe pockets in the disk G, turns forward the axle and starts the car.

Figs. 7 and 8 represent an alternative device for operating themechanism by the brake-shaft T. On the platform of the car rests agear-wheel,V,th rough which thebrakeshaft T passes loosely. Keyed orotherwise attached to the shaft T is a double ratchetwheel, 2), and onthe gear-wheelVis a doubleacting pawl, o YVhen the pawls are not engagedwith the ratchet, the shaft turns without turning the wheel; but whenthe pawls and ratchet are engaged the wheel turns with the shaft. Thepawls are disengaged by pulling them backward and holding them by meansof a plate, 12 which is provided with a hole for engagement with apin onthe pawl. Adjoining the wheel V and gearing with it is agea'r-wheel, IV,attached to the upper end of a shaft, to which the cord or chain S isconnected. lVhen the pawls o and ratchet o are engaged so as to turn thewheel V, the wheel V is also turned, so as to wind up the cord or chainS, and thus the parts areoperated si multaneously. Y

The shaft may be made square in its upper portion for the engagementwith a suitable crank when desired.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a car brake and starter, the combination, with the axle, thesleeve, and drum carrying the helical spring, of the disk G, keyed tothe axle and provided with depressions or pockets 9, for engagement withthe springpose specified.

2. The combination, with, the disk J, of the lever K, spring is, cord orchain S, and the brake-shaft, T, as: shown and described, for thepurpose specified.

3. The combination, with the sleeve 0 and the disk H, provided with thenotches h, of thepawl L, springs Z m, cord or chain M, and lever K, asshown and described, for the pur pose specified.

. 4. The combination, with the compressing clamp or brake P, of thecompressing-frame Q, cordor chain It, and brake-shaftT, as shown anddescribed, for the purpose specified.

5. The combination of the brake-shaft T with the cord or chain It andconnected devices, and the cord or chain S and connected devices, asshown and described, for the purpose specified.

6. The combination, with the brake-shaftT and connected devices, of thegear-wheels V WV, the double ratchet 12,, the pawl c and the adjusting-plate o, as shown and described, for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
